I have been trying to get my tune dialed in and I am still fighting with a lean issue on bank 1. It's a 98' camaro... 6 speed. Mods are:
Prc 5.3 heads ( milled to 59 cc's )
mls gasket
custom cam ( 227/228 ... 649/598 ... 111 lsa )
30 lbs injectors
ls6 intake / pp tb
long tubes and off road y-pipe with hooker catback
lid/smoothbellows
Pretty much all the basic mods... Car runs pretty good and I have got it tuned to 26 deg timing with no kr. Under WOT the ltft is 6-9% on bank 1 and 2-3 % on bank 2. At idle, bank 1 ltft is 14-17% and bank 2 is 4-6 %. I have done new plugs/wires, both o2 sensors, new intaked gaskets ( and checked for vacume leaks ) , new pcv system, new injectors and swapped coils on both sides as well as checking the o2 wiring. Also checked the exhaust for leaks ( EVERYWHERE ) ... Is there something I am missing? Please take a look at my tune and log ( this is the latest log and it's only idling.... did the rafig process ... also the log is pre-rafig adjustment, but the ltft trims have not changed since ). Any ideas would be great, as I am out of them :help:
